According to UL standards, you must have 1 spare digital receiver for how many active digital receivers?

The correct answer indicates that for every five active digital receivers, one spare digital receiver should be maintained according to UL (Underwriters Laboratories) standards. This requirement is essential for ensuring continuous operation and quick recovery in the event of a failure or malfunction of one of the active receivers.

Having a spare receiver allows for immediate replacement, minimizing downtime and maintaining the effectiveness of the security system. This practice is particularly important in alarm systems where reliability is paramount, as it ensures that the protection remains uncompromised even if a component needs to be serviced or replaced.

The UL standards are designed to enhance safety, reliability, and efficiency in alarm systems; therefore, adhering to this guideline helps organizations comply with industry regulations and maintain a high standard of security.
